Abstract
This invention relates to the clarification of natural waters containing turbidity-causing components. This method comprises the addition of a stable colloidal silica suspension and water based polymeric coagulant to the turbid water. The components of the invention may be added independently, or blended together so that addition is simultaneous. The colloidal silica may also be conditioned by passing over a cationic exchange resin prior to addition of cationic polymer.
